The invention relates to the technical field of jacks, in particular to a pull rod folding type airplane jack which comprises a hydraulic driving assembly and at least three sets of supporting assemblies, the hydraulic driving assembly is composed of a driving body, a driver and an oil tank, the driver is installed at the lower end of the driving body, and the oil tank is installed on the outer side face of the driving body. The driving body is connected with the driver through an oil pipe, a fixing ring is arranged in the middle of the driving body, the supporting assembly comprises an upper support, an inclined supporting column and a lower support, the upper support and the lower support are fixedly installed at the upper end and the lower end of the driving body respectively, and a folding pull rod is further hinged to the fixing ring and the lower support. The other end of the folding pull rod is further hinged to an inclined supporting column, and the other end of the inclined supporting column is hinged to the upper support. Through mutual cooperation of the supporting assembly and the folding assembly, when the device needs to be folded and unfolded, rapid folding and unfolding of the jack are achieved through the folding pull rod.
